👉 HQ: Infection is a biological process where pathogens, such as bacteria, viruses, fungi, or parasites, invade and multiply within a host organism, leading to disease. When an infection occurs, these microorganisms breach the body's defenses, often through breaches in physical barriers like the skin or mucous membranes. Once inside, they can cause damage by producing toxins, consuming host resources, or evading the immune system. The severity of an infection depends on factors such as the type of pathogen, the host's immune response, and the site of infection. Treatment typically involves antimicrobial therapies to eliminate the pathogens, along with supportive care to manage symptoms and bolster the body's natural defenses.
